Please keep all comments positive, constructive, and polite! ^^

Along with the Hard Worker base, I also happened to see this base by the same artist, and had to use it!

Are Diamond Tiara and Wind Sprint cousins?!
Welllllll, canonically no. In my next Gen though, Wind Sprint’s stepdad Quibble Pants is the younger brother of Daring Do (orphaned and separated at a very young age so they don’t realize they’re siblings till much later), and Daring Do ends up eloping with Dr. Caballeron, and Dr. Caballeron is the cousin of Filthy Rich, and Filthy Rich is the father of Diamond Tiara. So are they cousins? No, not at all. Is Diamond Tiara still gonna use their technical relations as an excuse to get closer to the hot buckball player on Wind Sprint’s rival team? Yes, absolutely xD

I image that Diamond Tiara’s crush on Rumble started quiet young, but between her feeling weirdly shy and Rumble being around Scootaloo all the time cause of their buckball team, I don’t think their romance started till they were nearly adults. And yes, she definitely has been extremely jealous of both Wind Sprint and Scootaloo since they both get along well with Rumble
